摘要：In this study, it was aimed to develop a measurement tool to determine the critical thinking skills of children. The Critical Thinking Skills Test for 5-6-Year-Old Children (CTTC) is composed of a total of 41 items and six subscales including interpretation, explanation, evaluation, inference, analysis, and self-regulation. As a result of the Confirmatory Factor Analysis performed for the validity of the test, it was found that X2/df (1,19) value was less than 5, GFI, AGFI, NFI, and CFI values were higher than .90, and RMSEA value was below 0.08. It was found that the Spearman correlation coefficient value applied for the criterion validity was over the moderate level and positive (r=0.66; p<0.05). The reliability of the test was analyzed by using the test-retest method. As a result of the analyses, it may be asserted that "The critical thinking skills test for 5-6-Year-Old Children (CTTC)" is a valid and reliable measurement tool.
